ජම්බු ගහෙන් වැටෙනවා

Euphemism for a girl attaining puberty. There are many other old and well established slang for the same such as Loku Lamayek Wenawa (ලොකු ළමයෙක් වෙනවා), Loku Wenawa (ලොකු වෙනවා), Malwara Wenawa (මල්වර වෙනවා), Geta Wenawa (ගෙට වෙනවා) (Literally 'become house confined' which is rather outdated term, which refers to rather outdated practice of confining a girl strictly indoors for few days, right after her very first menstruation)
